MS-102 Practice Question: Manage security and threats by using Microsoft Defender XDR
This MS-102 practice question tests your understanding of manage security and threats by using microsoft defender xdr. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A security administrator is configuring Microsoft Defender for Cloud Apps. The administrator needs to discover which cloud apps are being used in the organization and then block usage of unsanctioned apps in real time using a reverse proxy. Which two Defender for Cloud Apps features must be configured? (Select the two correct options.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Cloud Discovery
Cloud Discovery is the correct feature because it identifies which cloud apps are in use by analyzing traffic logs from the organization's network. This provides the visibility needed to determine which apps are unsanctioned. Conditional Access App Control is the correct feature because it uses a reverse proxy to enforce real-time access controls, blocking unsanctioned apps at the session level.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Cloud Discovery
Why this is correct
Cloud Discovery analyzes traffic logs to identify cloud apps used in the organization.

✗
App governance
Why it's wrong here
App governance manages OAuth app permissions and policies but does not discover apps or provide real-time proxy blocking.
✓
Conditional Access App Control
Why this is correct
Conditional Access App Control is a reverse proxy that can enforce access and session policies to block unsanctioned apps in real time.

✗
OAuth app permissions
Why it's wrong here
OAuth app permissions manage permissions for third-party apps but do not discover apps or block usage.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse App governance (which manages OAuth app permissions) with the reverse proxy functionality of Conditional Access App Control, or assume Cloud Discovery alone is sufficient for blocking, when it only provides visibility.
Detailed technical explanation
How to think about this question
Cloud Discovery works by ingesting traffic logs (e.g., from firewalls or proxies) via the Defender for Cloud Apps log collector or API integration, then cataloging apps against a cloud app catalog of over 31,000 apps. Conditional Access App Control integrates with Azure AD Conditional Access to route user traffic through the Defender for Cloud Apps reverse proxy, allowing granular session policies (e.g., block download, block access) based on app risk scores. In a real-world scenario, an admin would first run Cloud Discovery to identify a high-risk app like a personal file-sharing service, then create a Conditional Access policy to block all access to that app in real time.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
